what's wrong in gnus-topic-mode with nnimap?

[Easior Lars]

Hi, all.

I works in gnus with the setting

,----------------------------------------------------------
| (add-to-list 'gnus-secondary-select-methods 
|         '(nnimap "GMAIL"
|                 (nnimap-address "imap.gmail.com")
|                 (nnimap-user "xxx@gmail.com")            
|                 (nnimap-server-port 993)
|                 (nnimap-stream ssl)
|                 (nnir-search-engine imap)
|                 (nnimap-inbox "Inbox")
|                 (nnimap-fetch-partial-articles "text/")))
`----------------------------------------------------------

It is always fine. However, there is a defect that is boring me long
time. When I start up gnus with 'm+x gnus', I will see 

   ,----------------------------------------------
   | |   3[     0|  0]     * :nnimap+GMAIL:[Gmail]
   `----------------------------------------------

in the gnus-topic mode. It is weird that there is nothing in this
group and it can't be entered into. The report of bugtrace is as
follows

,------------------------------------------------------------------------------------------------------------------------------------------
| Debugger entered--Lisp error: (error "Couldn't activate group nnimap+GMAIL:[Gmail]: NO (NONEXISTENT) Unknown Mailbox: (Gmail) (Failure)")
|   signal(error ("Couldn't activate group nnimap+GMAIL:[Gmail]: NO (NONEXISTENT) Unknown Mailbox: (Gmail) (Failure)"))
|   error("Couldn't activate group %s: %s" "nnimap+GMAIL:[Gmail]" "NO (NONEXISTENT) Unknown Mailbox: (Gmail) (Failure)")
|   gnus-select-newsgroup("nnimap+GMAIL:[Gmail]" nil nil)
|   gnus-summary-read-group-1("nnimap+GMAIL:[Gmail]" nil t nil nil nil)
|   gnus-summary-read-group("nnimap+GMAIL:[Gmail]" nil t nil nil nil nil)
|   gnus-group-read-group(nil t)
|   gnus-group-select-group(nil)
|   gnus-topic-select-group(nil)
|   call-interactively(gnus-topic-select-group nil nil)
`------------------------------------------------------------------------------------------------------------------------------------------

It is annoying that this group can't be deleted by 'G+DEL'. 

Anyone can help me?

Thanks in advance.

Just kill it with `C-k'.  Gmail is reporting a group that doesn't exist.

`c-k' does not take effects. In fact, this group will appear again
after gnus restarts next time.

It's possible that you're seeing something that I ran into a while
earlier. When `nnimap-get-groups' is called, to retrieve all the names
of the groups on the server, it sometimes reads the group names
incorrectly if they have characters that confuse the call to `read'. Try
edebugging nnimap-get-groups and stepping through it until the response
comes back from the LIST command, then look at the buffer and see what's
there. It's possible a group name is being read incorrectly.

It's also just possible that gnus is somehow barfing on the imaginary
"[Gmail]" group that gmail likes to make. But I was able to visit the
server's group list from the *Server* buffer and just kill the group
there, as Lars mentioned.

If it's really mis-reading the group name, you can try fooling with the
local patch I use, which is ugly and probably highly dangerous for
reasons I haven't thought of, but at least Works For Me:
